Fawny coloured Deer Shield
This common wood-rotting mushroom has a variable season. It is prolific in summer and autumn, but if conditions are mild enough, it can appear as early as April or early winter if the weather is favourable.
The Deer Shield or Deer Mushroom (Pluteus cervinus) is one of the most common Shield mushrooms; and like nearly all of this genus, it is found on dead wood, stumps, logs and also wood chippings. It is a saprobe; getting nutrition from the dead wood and essentially breaking down the organism. It’s all part of life’s beautiful tapestry.
The cap of this particular Pluteus is smooth with variable colouring; mainly shades of brown (fawny like), but it can be paler and young specimens can be quite dark, as shown in the photo below. Subtle streaks can be seen radiating around the surface. Most often there is a slightly prominent central bump (umbo).
All mushrooms in this genus have a pink spore print and their gills are ‘free’ from the stem (See my other post on the Willow Shield mushroom here). They are initially white in colour, but over time they take on a pinkish hue as the spores mature. This is a good identification characteristic, albeit dependent on its age! Look around for older specimens if you can.
The stem is white and often becomes streaked with darker yellow-brown fibres as it ages. Also take a look at the base, where it usually is slightly swollen.
Edibility-wise there’s not much going for our lovely Deer Shield, but it still is edible (although it may not agree with some). The flesh is white, delicate and thin with a slight odour and taste similar to radish.

Why the Deer name?
When I was first aware of the common name, I assumed that ‘Deer’ was simply in reference to the colour. But apparently this is not so. Under the microscope, small cells (known as cystidia) present on the edge of the gills, show long protusions that are crowned with two tiny ‘horn’ shapes which resemble antlers – hence the ‘deer’ reference. Cervinus is also derived form cervus which is Latin for deer. You learn something new everyday!
I hope have luck finding these handsome mushrooms some time soon, as well as any others you may find along the way. Enjoy.
